“but so did Mexican marijuana farmers”
How so ? If Prop19 had passed, Californians would have grown their own and the price would have fallen. Basic economics — more supply = lower prices. Demand would not have increased anywhere near enough to offset the new glut of supply.
So Mexican farmers would have lost more if Prop 19 had passed. As it is, their profits are guaranteed to continue.
Why did Mexico’s president urge the passage of the bill? He knew we had to buy the buds at least somewhere; also, Mexicans would do the picking Americans wouldn’t do.
Imagine how this would have changed things for children in California: “When I grow up I want to be a pot farmer”.
